Verstaendlichkeit verschiedener Sprachausgabemodule - Ein experimenteller Vergleich

In recent years automatic voice output has become a new component in the field of man-machine communication. An important factor for the acceptance of voice output is its intelligibility. A comparison of the intelligibility of voice output modules shows that good voice intelligibility can be achieved by full synthetic speech as well as by parametric coding or waveform coding techniques. The decisive factors are the effort required to create a vocabulary and for the latter two approaches the choice of a suitable speaker. However, parametric coded and fully synthetic speech are still clearly felt by test persons to be unnatural. (IITB)
